Cell Phone Jog

I can get a good jog in whenever my cell phone goes off (on vibrate mode no less). It always seems to go off in the library so I haul ass to someplace semi-private to answer the phone and not bother others. Unlike 80% of the other people in this library when their cell phones go off (usually with full volume of ring tones). FYI: if you see me jogging just get out of my way as I'll take you down due to sheer momentum. Second FYI: empty study rooms (not likely at finals time) and the copying room count as semi-private areas, not next to me at a table.
